Title: Paper width detector, sheet feeder and image forming device
Inventor: ENDO MICHIAKI
IPC: B65H11/00
Filed: 1994-02-10
Abstract: PURPOSE:To prevent occurence of wrong detection of paper width due to a difference taking place in a movement starting direction of paper width regulating members by pinching a moving piece of slide volume between two members provided on a movable paper width regulating member side so as to be connected to the movable paper width regulating member side. CONSTITUTION:A lever 50 on side of a rack 34 L which pushes the moving piece 46 of a slide volume 40 linking with the movement of the rack 34 L is rotatably provided, and one end of the lever 50 is energized by a spring 52 so that the lever 50 is pushed to the moving piece 46 of the slide volume 40. The moving piece 46 is retained under such a condition that it is pinched between the lever 50 and a bumping rib 48 by always bringing the lever 50 in contact with the moving piece 46 of the slide volume 40 by means of energy of the spring 52 so that any play between the rack 34 L and the moving piece 46 of the slide volume 40 may be prevented from occur ring even though a side guide, i.e., the rack 34 L is moved right or left. Therefore, the occurrence of wrong detection of paper width due to a difference taking place in a movement starting direction of the side guide is prevented so that accurate paper width detection can be carried out without any error.

Title: Speed regulator for roller conveyor
Inventor: MARUOKA KENJI
IPC: B65G13/075
Filed: 1980-03-25
Abstract: PURPOSE: To restrain the load carrying speed from rising above a given speed, by a method wherein a cam is provided to an arbitrary one of the plurality of rollers rotatably disposed on a supporting frame, and a dead weight contacting with and separating from the cam is pivotally connected to the supporting frame.  
     CONSTITUTION: A roller frame 9 is installed inclining downwardly with respect to the load carrying direction A, and a load is carried on rollers 13. Thereupon, together with the rollers 13, a speed regulating roller 14 is also rotated in the same direction, and a hexagonal star cam 16 integral therewith rotates in the B direction. When the cam 16 contacts with a projection 19 by said rotation, a dead weight 17 pivots in the C direction on an axis 18 by the rotational force acting on the projection 19 in the B direction. When the projection 19 and the cam 16 separate from each other, the cam 16 contacts with a projection 20, causing the dead weight 17 to pivot counter to the B direction. Then, similar actions are repeated. Thus, by the longitudinal rocking of the dead weight 17, the damping force of the speed regulating roller 14 is produced to decelerate the load carrying speed.

Abstract: PURPOSE:To enable a ventilation of room air to be performed while a function of window is left as it is by a method wherein ventilation means is arranged for moving or replacing air within two spaces partitioned by a light accepting body mounted on a frame and by the frame. CONSTITUTION:An oxygen concentration sensor is used as a sensor 16 and if a switch 18 is set at its automatic position, a stove 1 is continuously ignited to cause a concentration of oxygen in a room to be decreased, a signal is sent from the sensor 16 to a control means 14 before the value shows a dangerous concentration, a motor 13 is driven to perform a discharging and a suction to automatically keep the room air at a safe concentration of oxygen. When a receiving sensor is used as a sensor 16, a state in which the stove 1 already starts to burn is transmitted from the receiving sensor 16 to the control means 14. The control means 14 may drive the motor 13 at once for 1min every time a 30min is elapsed so as to perform a discharging or sucking of the air and perform an automatic ventilation of room air.

Title: Electron beam exposure
Inventor: HAMAGUCHI SHINICHI
IPC: H01J37/317
Filed: 1984-02-29
Abstract: PURPOSE:To improve the precision of pattern drawing image while not lowering productivity by a method wherein the peripheral part of pattern is not irradiated until the effect of preceding shot is attenuated at specified time interval while any part other than the peripheral part of pattern is irradiated at specified time interval shorter than said time interval. CONSTITUTION:Within the electron beam exposure irradiating specified pattern by electron beam, a pattern 2 can not be exposed at one time due to the structure of device therefore the pattern 2 is irradiated by means of irradiating all of small patterns 3 starting from point (a) to point (c) through point (b) and vice versa one by one. The peripheral parts are irradiated only after the effect of preceding shot is attenuated since the important factor of precision of pattern 2 is the precision of peripheral parts 2a, 2b, 2c and 2d. However, the precision of pattern need not be taken into consideration at the central part of pattern to be exposed to the extent wherein resist may be left within allowable range.

Abstract: PROBLEM TO BE SOLVED: To provide a lens barrel that large force and large power consumption are not required for a switching action on a condition that instantaneous operation and load are imposed by a method in which one part of a power transmission mechanism leading to a distance adjustment ring from a motor is directly connected and disconnected. SOLUTION: Since a manual adjustment barrel 6 is set above a distance adjustment barrel 5 and the key 5b of the barrel 5 gets in the inside straight advance key groove 6a of the barrel 6, so that the rotation of the barrel 6 can be transmitted to the barrel 5. The straight advance positions of the barrel 5 with respect to a moving barrel 4 and the lens group L1 of a holding frame 1 are changed by the change of the relative angle of the barrel 4 and the barrel 5 so that the focusing action of this lens barrel can be executed. On the other hand, power from a lens driving motor 12 is passed through deceleration gear trains 9a, 9b, 9c and 9e from the pinion 12a of a motor shaft through deceleration gear trains 11a and 11b and a clutch mechanism 10 so that an internal gear 6b formed at the inside diameter side of the barrel 6 is turned.  Thus, the driving of an automatic focusing action is realized.

Title: Fourier transformation type infrared film thickness measuring apparatus
Inventor: EGUCHI KINYA
IPC: G01B11/06
Filed: 1985-03-01
Abstract: PURPOSE:To obtain a Fourier transformation type infrared film thickness measuring apparatus available for accurate measurement of film thickness even if the specimen is covered with the film of high absorbability. CONSTITUTION:The apparatus is provided with an infrared polarizer 16 between infrared interference filler 14, specimen 17 and light source 9. When a reflection infrared spectrum is measured by a Brewster's angle, a vertical polarized light measurement assumes pronouncedly overlapped interference spectrums caused by the thickness of the thin film and a horizontal polarized light measurement does not include this feature at all and consequently, when the difference spectrum of both measurements is obtained, the spectrum obtained shows only an interference spectrum by the thickness of the film. By Fourier conversion of this difference spectrum, a noiseless cepstrum including only the side burst caused by the film thickness can be obtained. The higher calculation accuracy of the Fourier conversion, the narrower the wave length range of the infrared light. Further, many thin films do not show absorbability in the range of 2,700-1,800cm and by using an interference filter 14 transmitting the beams of light of this range, considerations not only of the calculation accuracy of the Fourier conversion, but also of the absorption by the thin film can be eliminated.
